I don't 'train' so much as just 'ride'.
Sometimes hard, often not so hard.
No coach, no group riding, so recreational.
At 76+ I don't hold any illusions about 20 mph averages over 100 mile rides, I'm thankful that I can manage 15miles in an hour a couple times a week. Yesterday I didn't quite complete my planned 26 miles, instead taking a shortcut at the end after 21 due to the 8 - 20 mph headwinds I'd been facing, just over 2 hours.

Downhill this section, fast!
Looking back where I'd come from:
Hills here are daunting! More than once I had to dismount, walk instead of ride. No shame in that as my HRM tells me I've crossed the 160 BPM redline already.
Still, it was a worthwhile endeavor! I feel fine this morning, anticipate getting in another stretch today out in the better conditions the weather service is predicting. I'll take it easier today than yesterday for sure.
